Radiochemical methods of analysis based on the dependence of interphase distribution of radioactivity on the change of test element/reagent ratio Pt. 1

A group of radioanalytical methods is considered, in which the change of the test element to reagent ratio is achieved by means of isolations using equal quantities of reagents from multiple volumes of the analyzed solution. These methods allow the application of non-isotopic radioindicators and radioactive reagents to increase the sensitivity and selectivity of the analysis more than substoichiometric methods of isotope dilution and radiometric corrections. In this first part the methods of isolation from multiple volumes of analyzed solution with the use of isotopic radioindicators, of non-isotopic indicators, of radioactive reagents in the presence of interfering elements are considered.
